Quorum sensing Choose one: A. occurs in the gut to signal hunger. B. coordinates biofilm formation via chemical signaling among cells. C. triggers endospore formation. D. triggers washout in continuous culture.

Coordinates biofilm formation via chemical signaling among cells. (Ans B)

Explanation:

Quorum sensing in bacteria uses to regulate certain expressions such as phenotype which in turn, coordinate their behavior. Some common phenotype examples are biofilm formation, motility, and virulence factor expression.

Some bacteria have the ability to use quorum sensing to regulate nitrogen fixation, bioluminescence, and sporulation. Quorum sensing regulates genes involved in biofilm development, it helps to promote biofilm dispersion and upregulates the synthesis of surfactant molecules. Quorum sensing and biofilm development are known as social bacterial behaviors.
